Effect of storage conditions on the viability of a population of antibiotic-producing actinomycetes

Abstract

It was established that keeping roseofungin like type antibiotic producer Streptomyces roseoflavus Arai 23/791 and producer of a fooder preparation S. antibioticus 25/779 in liophylized state changes population structure. Types of colonies, varying on viability, сultural-morphological attributes and biosynthetic activity are revealed. Morphological variability of depends on composition of nutritional media.
